Patent GB-688337-A (GB)
IPC: G01B3/48
Abstract: 688,337. Gauging screw threads. MANDER, H. W. Nov. 7, 1951 [Dec. 15, 1950], No. 30697/50. Class 106 (ii). A " go " and " no go " screw thread gauge 20, 21 is carried on a spindle 16 mounted in bearings 14 carried in two lugs 13 of the gauging head 10. A drive from an electric motor 12 is taken via a flexible shaft 11 to the head 10. The flexible shaft 11 terminates in a square end 23 which engages a frusto-conical member 24. The shaft 16 is mounted so as to have a limited amount of end play and carries in between the lugs 13 a wheel 17 provided with two rubber driving bands 19. The driving bands 19 are arranged so that.there is a slight clearance between them and the driving member 24 when the spindle 16 is in its central position. Slight pressure in either axial direction will engage one or other of the driving bands to rotate the screw gauges in clockwise or counterclockwise directions according to the direction of pressure. In use the gauge is presented to the screw thread to be gauged, the slight pressure caused by resistance to entry into the thread being sufficient to engage the driving band 19 so as to screw the gauge into the thread. If it will not centre, the driving band 19 slips on the member 24. To remove the gauge from the thread the head 10 is pulled away from the thread and the opposite driving band is engaged to rotate the gauge in the opposite direction and withdraw it from the test piece. In a modification the flexible driving shaft 11 may be eliminated by incorporating the driving motor, which may be an electric or compressed air type, in the gauging head itself. The thread gauges 20, 21 are held in a hollow taper section in each end of the shaft 16 and are interchangeable with other screw thread gauges. The operation of the " no go " gauge 21 is similar to that described above for the " go " gauge.

Title: Stabilisation of nitrocellulose after pressure boiling
IPC: C08B5/08
Filed: 1978-06-16
Abstract: This invention relates to the final stabilisation of nitrocellulose after pressure boiling and, in particular, to the final stabilisation of pressure-boiled nitrocellulose suitable for use as collodion wool for lacquers. Final stabilisation of nitrocellulose is required in order to eliminate instability caused by secondary reactions in the pressure-boiling process and to adjust the chain length of the nitrocellulose. No satisfactory stabilisation treatment has hitherto been found, attempts having resulted in processes involving complicated equipment or long treatment times. This invention provides a stabilisation treatment involving a combination of a centrifuging step at 1000 to 1600 rpm and a washing treatment with from 1 to 10 parts of warm water. The washing treatment is effected for a period of only 15 to 30 seconds and thereafter the nitrocellulose is taken up with water and removed.

Title: Improvements in or relating to metal detectors
IPC: G01V3/10
Filed: 1978-08-07
Abstract: In a metal detector which utilises two different frequencies ground signals are substantially cancelled so as to improve the sensitivity of the metal detector. Transmitter coil 1a is fed with frequency f1 of 1Kc/s to 100Kc/s and f2 ten times as great and the induced signal in receiver coil 1b is fed via diplexer 5 over two channels each including amplifier 8,9 mixer 10,11, filter 12,13 to comparator 14. The gain of amplifier 9 is adjusted relative to amplifier 8 in accordance with the ratio f1/f2 so that the output signals at 12,13 are substantially equal for the ground signals and these cancel out in comparator 14. The signals due to the metal object have similar amplitudes at the two frequencies and due to the different gains of 8 and 9 an unbalance signal is produced by comparator 14. Signals originating from ferrite materials may be cancelled in the low frequency path by feeding an L.O. frequency, the phase of which is controlled by means of a feedback loop, to mixer 11. <IMAGE>

Title: Loop metal body detector assemblies
IPC: G01V3/10
Filed: 1979-06-12
Abstract: To enable selectivity as to the detection of metal objects such as vehicles by a loop detector assembly, a relay 1 connected to a loop detector circuit 2 is operated when a vehicle is detected at low sensitivity over a buried conductive loop 3, operation of the relay causing sensitivity to increase. Thus, the sensitivity of the assembly is automatically increased from a low to a high value after detection of a vehicle at low sensitivity. The sensitivity of the arrangement automatically reverts to the low value after the vehicle has ceased to be detected. The assembly may be operated at maximum sensitivity by operating a switch 4 in parallel with relay 1. Alternatively minimum sensitivity can be obtained by operating switch 5. The assembly can be provided with a time delay so that relatively fast moving objects are not detected. <IMAGE>
